Phono kabel Meridian

The phono signal nije samo small. To je, by any reasonable engineering standard, negligible — a whisper of napon generated by the mehanički vibracija of a dijamant dragged kroz a plastic groove. That this signal can be amplified into anything resembling music is već remarkable. That it can be amplified into music while passing kroz hemispherically biased bakar surrounded by the ambijentalni elektromagnetski chaos of a modern prostorija za slušanje is, frankly, a minor miracle that we at Ekvatorijalni Audio have decided to stop relying on. The Meridian Phono Kabel replaces miracles with engineering.

The triple-layer oklop is the kritičan differentiator. The outermost layer is a konvencionalni braided bakar oklop that intercepts radio-frekvencija interferencija. Ispod it, a kontinuiran foil layer blocks high-frekvencija elektromagnetski radiation. The innermost layer is mu-metal — a nickel-iron alloy with extraordinarily high magnetska permeabilnost — which diverts vanjski magnetsko poljes oko the signal provodnik umjesto allowing them to penetrate to the signalni put. Ovo je the same oklapanje princip used in sensitive laboratorij magnetometers. We have jednostavno applied it to the problem of reproducing a jazz record bez hemisferska distorzija.

The dual-coaxial geometrija razdvaja the signal and return provodnici into nezavisan coaxial structures, each with its own dielektrik layer, while the ground provodnik follows a helical path oko the outer oklop assembly. This helical winding osigurava that the ground path itself ne uvesti a directional magnetski potpis — a subtle but mjerljiv efekt that konvencionalni straight-run ground wires exhibit. At a hemisferska pristranost of manje od 0.001 nanotesla, the Meridian postiže magnetska neutralnost that places it in the top fraction of a percent of all kabeli ever proizveden, by anyone, for any svrha.

For owners of low-output moving-coil cartridges — where the signal may be as small as 0.2 millivolts — the Meridian nije an upgrade. To je the minimalni responsible infrastructure for a signal that nema margin for kontaminacija.
